This does still occur without any other fabric mods aside from the API

Thanks for reporting! That's ... unexpected 😄
I saw the conversation on Fabricord as well.

~~Does this line show every time?

If so it might be a world - related issue, not really sure though. Could you try reproduce the line with new world? Or does it happen without simpleauth?

Have you changed any of the settings in SimpleAuths's config file? Especially premiumAutologin, which is rather new ..?~~

Edit: comment bellow is probably better.

# The crash happened outside the Java Virtual Machine in native code
Makes me think it may be an error with hashing ... Could you try enabling different hashing algorithm and see if it helps?

Replying in order

1. This line shows up with the same two mobs every time the crash occurrs, the only variation may be the actual UUID and numbers, but always with a Pig and a Zombie

2. Fresh world, (deleted and recreated using same seed, 433854927151926720

3. No i have not changed any settings as i do not understand the settings structure

4. Tests with bcrypt show success, thank you

I am using this docker container for my minecraft server itzg/minecraft-server:latest
If you want i can zip my whole minecraft server folder for you to test with? i do not have any sensitive information on my server at the moment

[samolego]

Humm, this would make debugging easier, however, it may be server-specific. But if you don't mind sharing the zip, I'd be happy to see it.

No i have not changed any settings as i do not understand the settings structure

Ahm, this concerns me a bit. Any ideas to make it clearer? 😉

[Merith-TK]

this is a full zip of my current server, (the only difference between the non-working and the working, is that when it is working, there is now an entry for GuardDawg2021 on the wold data and SimpleAuth, along with BCrypt being enabled)

I'm having the same issue but in singleplayer, i've looked up how to fix it, nothing worked so far, however... i am using cracked minecraft currently, is this issue possibly caused by the game not being the official version?

[ghost]

also, i'm not using the mods JNI or Argon2

[samolego]

singleplayer

Mod is meant to be used on the server :) ..?

also, i'm not using the mods JNI or Argon2

Those are packed inside the SimpleAuth.
